4 * The base implementation of methods like `_.dropWhile` and `_.takeWhile`
5 * without support for iteratee shorthands.
6 *
7 * @private
8 * @param {Array} array The array to query.
9 * @param {Function} predicate The function invoked per iteration.
10 * @param {boolean} [isDrop] Specify dropping elements instead of taking them.
11 * @param {boolean} [fromRight] Specify iterating from right to left.
12 * @returns {Array} Returns the slice of `array`.
